PCV? Or something worse.

[Moparornocar0346]

Ok guys. So I just wanna add that I did my plenum job here a few weekends ago and been kinda keeping my eye on my oil for consumption signs. It’s still using oil. I will add that my cable cover is leaking. But I added some oil it was either Wednesday or Thursday. Checked it earlier and imma half quart low. I would see a valve cover leaking that much within that time span. I will say that my pcv is aftermarket and Not Mopar. I have read a few places that not to get them anywhere else but dealer. Is this true and why? All opinions will greatly appreciated

Reliability is why that gets said. If it rattles it's fine

You should also do a compression test to really diagnose the issue

Compression test? For the rings right?

A basic compression test will tell you whether or not your chambers are nice and sealed or if you have either a ring seal issue or valve stem seal issue.

If you don't get very good results, adding an ounce or two of oil then repeating the test will confirm if it's a ring issue because the oil will perfect the seal between the rings and cylinder walls. If compression rises by more than 10-15psi, bad rings. If it doesn't change much I'd be looking at valve seals
